5 Step Work Process of Hydraulic Core Drilling Rigs
- Preparation: Level the ground, self-level the equipment, adjust the mast according to the design requirements, dig the mud pit, and connect the mud pump and other preparatory work.
- Casing Installation: Just like laying the foundation for a building, drilling requires casing installation before drilling begins. The casing must be installed to reach the bedrock.
- Drilling Begins: The double-tube drill string assembly is lifted and connected to the power head, the mud pump is started, and drilling begins.
- Retrieve Core Sample: After drilling to a set depth, the inner tube fills with core samples. At this point, a hydraulic winch is used to lower the retrieval tool into the drill rod. The tool is then allowed to fall freely under gravity to the inner tube, and the core samples are retrieved.
- Recording: After placing the core samples, make a record. Once all the core collection is completed, remove the drill rods and casing from the hole. Finally, use cement to seal the hole and restore the site to its original state as much as possible.
6 Core Advantages of YG Full Hydraulic Core Drilling Rigs
- Faster Relocation: The modular design of the main machine, pump station, and mast allows for quick disassembly and transport with light trucks. Traditional rigs take 2 days to relocate, while a full hydraulic rig typically only takes 1 day. This means you can complete 1-2 more medium-sized projects per year, directly adding tens of thousands of dollars in revenue.
- Fuel Efficiency: The load-sensing hydraulic system delivers power as needed. Compared to traditional gearbox + clutch systems, it can reduce fuel consumption by 25-35% under the same working conditions.
- Higher Core Quality: The hydraulic feed pressure is infinitely adjustable, enabling “constant pressure/constant speed” drilling, which greatly reduces core blockages and mechanical breakage. The core recovery rate improves by 5-10% on average.
- Single-Person Operation: The integrated electro-hydraulic control system allows for centralized control of major actions (such as twisting and unloading drill rods, advancing, and retracting) via a handle. Experienced operators can complete most high-precision operations independently, reducing reliance on auxiliary workers.
- Self-Recording Data: Built-in sensors can record and output key parameters such as drilling pressure, rotation speed, and pump pressure in real-time. This data is not only a construction record but also a private database for analyzing formations and optimizing future drilling plans, allowing you to offer more accurate quotes and project time estimates compared to competitors.
- Wide Formation Adaptability: From soft soil to hard rock layers, the rig can adapt by adjusting hydraulic parameters instead of replacing complex gearboxes. This enables you to take on projects with varying geological conditions, and these types of projects often have 20% higher profit margins than conventional ones.
5 Reasons to Choose the Full Hydraulic Core Drilling Rig Over Traditional Machines
- Efficiency Equals Profit: Traditional rigs require stopping for rod changes and manual handling, making them inefficient. However, the full hydraulic rig features an automatic hydraulic power head for quick rod changes, improving efficiency by 30%. In day-rate projects, this directly translates to profit.
- Reliability Saves Money: Traditional machines have many mechanical components, which create multiple failure points and require significant maintenance. Full hydraulic rigs have higher system integration, and the lifespan of key hydraulic parts is predictable. The average time between failures is improved by about 40%, significantly reducing unexpected downtime.
- Precision Justifies a Premium: Traditional machines have rough feed control, leading to angled holes. Full hydraulic rigs offer smooth and precise feed control, paired with real-time hole deviation monitoring, achieving a nearly 100% hole straightness rate. High-quality boreholes form the basis for charging a technical premium to customers.
- Safety Equals Asset: Traditional operations require workers to handle tasks close to moving machinery, increasing risk. With full hydraulic operations, tasks can be remotely controlled from a safe distance, significantly lowering accident rates.
- Resale Value Is Savings: Traditional rigs have a residual value of less than 30% after 5 years. However, due to their advanced technology and reliability, full hydraulic rigs maintain a residual value of over 50% in the international second-hand market after 5 years. This makes it not just a tool but a valuable asset.
5 Application Scenarios of Hydraulic Core Drilling Rigs
- Core to Mining Exploration: As long as humans need mineral resources, we need to know what lies underground. Core drilling is the “gold standard” for obtaining true three-dimensional information of the underground, and is irreplaceable. The YG full hydraulic core drilling rig is one of the best tools to execute this standard.
- Core Tool for Key Metal Exploration: With the rapid growth of demand for key metals such as lithium, cobalt, and rare earth elements for the new energy transition, mineral bodies are often complex and niche, requiring precise drilling technology. The full hydraulic drilling rig is the best tool for exploring these mineral resources, enabling you to get accurate data.
- Technology Platform and Modular Upgrades: The full hydraulic rig is not just a drilling tool, but an open technology platform that can carry advanced modules such as real-time logging and directional drilling. As technology advances, it can be connected to tablets for real-time geological data analysis, ensuring continuous hardware upgrades without obsolescence.
- Automation and Labor Cost Savings: As drillers become more scarce and expensive globally, drilling machines that rely on traditional manual operation are losing their competitive edge. YG’s full hydraulic drilling rig offers automation and single-operator capabilities, reducing reliance on skilled workers and maximizing efficiency while lowering labor costs.
